Substitute Part Grouping Explanation

Substitution for the USV1H4R7MFD1TP is based on strict electrical and mechanical parameter matching within the Nichicon aluminum electrolytic capacitor product line. The following criteria determine valid substitutes:

Critical Matching Parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 5000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)

Mechanical Compatibility Parameters:

Lead Spacing: 0.098" (2.50mm) or 0.197" (5.00mm) acceptable
Size / Dimension: 0.197" Dia (5.00mm) (exact match required)
Height - Seated (Max): 0.315" (8.00mm) (exact match required)

Two substitute parts meet these criteria, differentiated by lead spacing configuration.

Engineering Selection Recommendations

Both UTS series parts are active production components from Nichicon and provide direct substitution for the obsolete USV1H4R7MFD1TP. Selection between the two substitute parts depends on PCB layout requirements:

UTS1H4R7MDD1TE features 0.197" (5.00mm) lead spacing and is suitable for applications where increased lead separation is acceptable or preferred for PCB routing.

UTS1H4R7MDD1TP features 0.098" (2.50mm) lead spacing, matching the original part's lead configuration, and is the preferred choice for direct PCB replacement without layout modification.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. Active product status guarantees ongoing availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can UTS1H4R7MDD1TE and UTS1H4R7MDD1TP be used interchangeably?

A: Both parts are electrically equivalent and meet all critical electrical parameters. Interchangeability depends on PCB lead spacing design. UTS1H4R7MDD1TE requires 0.197" (5.00mm) hole spacing, while UTS1H4R7MDD1TP requires 0.098" (2.50mm) hole spacing. Verify PCB layout before selection.

Q: What is the difference in ripple current ratings between the main part and substitutes?

A: The USV1H4R7MFD1TP specifies 29 mA @ 120 Hz and 44.6 mA @ 10 kHz. Both UTS substitutes specify 12 mA @ 120 Hz and 30 mA @ 100 kHz. These differences reflect measurement conditions and frequency specifications but do not affect functional equivalence for general purpose applications.

Q: Are the UTS series parts suitable for direct replacement on existing PCBs?

A: UTS1H4R7MDD1TP is suitable for direct PCB replacement due to matching 0.098" (2.50mm) lead spacing. UTS1H4R7MDD1TE requires PCB modification to accommodate 0.197" (5.00mm) lead spacing.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both UTS substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with HTSUS code 8532.22.0020, matching the original part's regulatory status.

Q: Why is the USV1H4R7MFD1TP marked as obsolete?

A: Product obsolescence reflects Nichicon's discontinuation of the USV series. The UTS series provides active production alternatives with equivalent electrical and mechanical specifications.
